Boxster 2.5 white sludge at water pipe connection

Recommended Posts

Hi, I am trying to bring a 99 Boxster (2.5 Tiptronic RHD) back from the dead. I am in the process of removing the engine and gearbox and noticed some white sludge at one of the water pipe connections.

I am not expecting too much from this motor as it had no oil in when I took delivery of it but I was wondering if this could be an indication of where things started to go wrong?

The car also only had about 2 liters of clean water in the coolant circuit (no antifreeze). Quite sad considering it only has 126k Kms on it...

Bigger question is where did it come from?  In good health, these engines do not do that...………...

An update on the project so far... The engine and gearbox removed and the heads are taken off. The inside of the engine actually looks a lot better that the outside (guessing the disintegrated oil-breather bellow had something to do with it).  I did see that the Cylinder 456 head was missing a water channel plug which was lying next to the inlet cam...

Is this a common occurrence?

Also I would have expected to see a lot more water in and around the cams of this head but I could not see any?

 

Any suggestions on a engine rebuild manual? The Bentley Service manual does not really cover any specific engine repairs...IMG_7265small.thumb.jpg.0f135d83cef2ad16812016cd4c7f29dd.jpg

Porsche never published any information about rebuilding these engines as they did not want that done in the field.  Jake Raby runs online and in person schools on the subject, and is the only source for printed material on the required torque specs, etc.
